EDMONTON, Alberta--(BUSINESS WIRE)--Entos® Pharmaceuticals (Entos), a clinical-stage genetic medicines company committed to using its Fusogenix™ PLV™ technology to develop cures and improve the lives of patients and their families, today announced the publication of a research article in Cell. The article, titled “Safe and Effective Delivery of DNA and RNA Using Proteolipid Vehicles,” details the development of a novel delivery platform for nucleic acid medicines that overcomes the limitations of current delivery systems. Incorporating fusion associated small transmembrane (FAST) proteins into a proteo-lipid vehicle (PLV), or FAST-PLV, this new platform can effectively deliver mRNA or plasmid DNA into a wide variety of cells and tissues with low immunogenicity and broad distribution throughout the body. Entos led research that involved collaborators from the University of Alberta, Dalhousie University, Oisín Biotechnologies and Aegis Life, Inc., to develop the platform and conduct studies demonstrating its advantages over lipid nanoparticle (LNP) delivery systems. The research findings were published by Cell online this morning and will appear in the journal’s September 19th print issue.
“Currently AAV and LNPs are the main delivery platforms for genetic medicine. Both platforms have significantly advanced the field with approved therapies and vaccines for a variety of serious and often life-threatening diseases,” said John Lewis, Ph.D., senior author of the study and Bird Dogs Chair of Translational Oncology at the University of Alberta and CEO of Entos Pharmaceuticals. “Despite these advancements, gaps remain in the ability of current technologies to fully realize the potential of genetic medicines. We designed the FAST-PLV platform to bridge these gaps and deliver on the promise of genetic medicines that patients urgently need.”
The FAST-PLV platform is a fusion-powered delivery system for genetic medicines that combines aspects of viral and non-viral approaches to leverage a completely new mechanism for intracellular delivery of RNA and DNA. While AAV and LNP rely on endocytosis, the FAST protein enables direct fusion of the PLV to the plasma membrane of target cells. This substantially improves the potency and tolerability of genetic medicines, while enabling the development of formulations that are inherently non-liver tropic, enabling the delivery of therapeutic doses of nucleic acid therapies to cells and tissues throughout the body. In this work, the platform was evaluated for safety, efficacy, and biodistribution in various animal models, as well as demonstrating that the FAST-PLV platform is non-immunogenic, which allows for repeat dosing of genetic medicines.
“I am incredibly proud of the strides we've made in genetic medicine with our FAST-PLV platform. This breakthrough not only underscores the potential of our technology to overcome current limitations in gene delivery but also reinforces our commitment to developing safer, more effective, and re-dosable therapies for patients. The publication of our work in Cell is a significant milestone, and we believe it marks the beginning of a new era in the field of genetic medicine,” said Arun Raturi PhD., senior author and CSO of Entos Pharmaceuticals.
FAST-PLVs form the basis of Entos’ Fusogenix™ PLV™ delivery platform, which is being utilized by Entos Pharmaceuticals to develop novel therapies for congenital generalized lipodystrophy, obesity, Stargardt disease and cystic fibrosis in addition to its clinical VAX-002 vaccine program. Entos and its valued partners are developing applications in the central and peripheral nervous systems, oncology, longevity and more.
